In order to comprehensively understand the specific noise generation process inside pressure reducing valves (PRV) and its existing research outcomes, the generation of noise in PRV with its research methods in China and abroad was summarized. Then, the current research status of noise reduction technologies was reviewed from two aspects: source and propagation. Based on analysis and summarization

Konvergens är ett möte mellan en dramatiker och en kompositör i ett försök att bejaka likhet och skillnad i jakt på en (omöjlig) samstämmighet. Det är ett elektroakustiskt verk för en musiker, en sopran och två skådespelare. Det är ett försök att skapa platser för möte och krock. Mellan människor och mänskliga viljor, och mellan konstarter och dessas egna logiker. Frågor uppstår om ägande, känsla

The extent to which a favorable lifestyle may lower cancer risk in subjects with a family history of cancer is unknown. We conducted a prospective study in two Swedish cohorts, the Malmö Diet and Cancer Study (MDCS; n = 25,604) and the Malmö Preventive Project (MPP; n = 16,216). The association between a favorable lifestyle (based on nonsmoking, normal weight, absence of excessive drinking, regula

Several concurrent developments are shaping the future of plastics. A transition to a sustainable plastics system requires not only a shift to fossil-free feedstock and energy to produce the carbon-neutral building blocks for polymers used in plastics, but also a rational design of the polymers with both desired material properties for functionality and features facilitating their recyclability. B

The script we are presenting below is one of four different scenarios from Violence & Learning by Henrik Bromander and John Hanse, which was performed at the International Brecht Society’s Symposium in Oxford in June 2016. The learning play Violence & Learning has been developed and performed in the context of left-wing activism in Sweden. The different variants of the play have partly bee

Boken redogör för de huvudsakliga resultaten av ett forskningsprojekt som undersöker rollen som skogsägare. Empiriska data insamlades genom semistrukturerade intervjuer som i många fall följdes av promenadintervjuer då skogsägarna visade upp och berättade om sina skogsbruk. Intervjuernas genomsnittliga längd var 2 timmar 6 minuter. 49 av 50 intervjupersoner var män men i många fall deltog även der

Background: Epidemiological data indicate decreased risk for development and growth of abdominal aortic aneurysm (AAA)among patients with diabetes mellitus (DM), but DM also goes with increased cardiovascular (CV)morbidity and mortality. We evaluated the effects of DM on mortality and CV morbidity after elective open AAA repair. Methods: This is a nationwide observational cohort study of patients

AbstractPURPOSE: To assess the relative influence of genetic and environmental effects on retinal vessel diameters and blood pressure in healthy adults, as well as the possible genetic connection between these two characteristics. METHODS: In 55 monozygotic and 50 dizygotic same-sex healthy twin pairs, aged 20 to 46 years, interpolated diameter estimates for the central retinal artery (CRAE), the

Spatial distribution information on population density is essential for understanding urban dynamics. In recent decades, remote sensing techniques have often been applied to assess population density, particularly night-time light data (NTL). However, such attempts have resulted in mapped population density at coarse/medium resolution, which often limits the applicability of such data for fine-sca

Background: Delayed cord clamping (DCC) after 180 s reduces iron deficiency up to 8 months of infancy compared to babies who received Early Cord Clamping (ECC) at less than 60 s. Experimentally DCC has shown to improve cardio-vascular stability. To evaluate the effect of delayed (≥180 s) group versus early (≤60 s) cord clamping group on peripheral blood oxygenation and heart rate up to 10 min afte

AbstractBACKGROUND/AIMS: To assess the relative influence of genetic and environmental factors on retinal arterial tortuosity and the association between tortuosity and various health indices in healthy young to middle-aged persons. METHODS: This cross-sectional study included 57 monozygotic and 52 dizygotic same-sex healthy twin pairs, aged 20 to 46 years, who were characterised by determination

Advanced 1-D models for secondary clarifiers aim to incorporate more realism by explicitly accounting for several phenomena that influence the settling process. For each of them a valid mathematical expression needs to be selected to obtain a calibrated model that can be used for operation and control. The presented work evaluates different available expressions for hinderedsettling based on long

An activated sludge process (ASP) consisting of a plug-flow reactor (PFR) and a non-ideal settler is modelled and analysed. One soluble substrate component and one particulate biomass are assumed. The biomass growth rate is described by a Monod function. The settler model includes hindered settling and compression. A model describing the steady-state behaviour of the ASP is derived which constrain

Rekonstruktion:Festen är ett labb som genomförs av grupperna Banditsagor (Malmö) och Skuggteatern (Umeå). Tillsammans undersöker de en form av scenkonst där publiken är aktörerna men inte behöver ta ansvar eller agera. Labbet pågår i en vecka och avslutas med två test i form av föreställningar. Det är dessa test som vi nu bjuder in till.Rekonstruktion:Festen är en rekonstruktion av ett fiktivt hän

A simplified activated sludge process (ASP) with one substrate and one particulate biomasscomponent has been analyzed with respect to its steady states. The ASP consists of a completelystirred biological reactor and a settler. The biomass growths according to the Monod function and the decay rate is constant. In the considered one-dimensional settler model, the biomass undergoes hindered settling
